Our Energy Recovery Systems integrate advanced energy recovery technologies and components into the HVAC system to capture the energy in the airstream — that would otherwise be exhausted to atmosphere — and use it to either pre-heat or pre-cool the outdoor airstream. Flat plate exchangers consist of alternating layers of plates that are separated and sealed with a heat or energy recovery core treating incoming air. Energy recovery systems help you maintain a comfortable relative humidity in your indoor environment by transferring the moisture from humid outdoor air to the exhaust airstream or adding moisture to the incoming ventilation air. Maintaining indoor air quality is vital to the health and well-being of a building’s occupants. Related Blog Posts:High Plume Dilution Fans | What is a High Plume Dilution Fan? If the system brings in 100-percent outdoor air, or is being modified to bring in 100-percent outdoor air with no recirculation, bypassing the energy-recovery device will reduce or avoid A cross-flow heat exchanger exchanges thermal energy from one air-stream to another in an air handling unit (AHU). This pre-heating or pre-cooling can lead to significant energy savings and a reduction in the building’s central plant size. That is a huge plus. Let’s assume you have a 4 Ton Unit ( Click Here to understand and interpret HVAC Tonnage ), and are required by code to introduce 25% fresh outside air (in this case … During the winter months the outside air is pre-heated prior to entering the air handler and during the summer the outside air is pre-cooled.
